Lucky you, in the last 3-4 days I've racked up around 5500 WUs (well over 150,000 requested credits) and had less then 30 WUs validated and less than 900 credits granted.

Obviously many of those work units will be waiting for other machines to return results before validation but last time I had the grid running SETI the granted credit seemed to be increasing everytime I hit refresh on the browser ...

Hang fire I'm sure it's in the process of getting fixed.

We're planning on doing some rigorous file deleting during the database outage tomorrow. I hope we can turn the corner before the validation queue hits 1M!

Matt, are you caught by this possibly unexpected filesystem effect?

Of course we thought of this. During our mini outage yesterday we shut enough things down to quickly access a single result directory, and created a new directory, and moved all the files there, etc. in order to "compress" the directory. The resulting directory had the same size as the old one. So this had no effect.

We'll see what the file deletion does, then go from there.

:-(

Waiting for validation 895,216 as of 0134hrs UTC time.

From the status page. Its growing, but slowly. Hopefully tomorrow the outage will clear some of that up.

This looks like it should be nicely interesting when you discover/uncover the full story.

Good luck, and thanks for suffering the feedback :)

I also have watched with interest as the validator queue has grown but it's not as bad as it looks. If you go to your account info and click "results" you'll see that results returned have "pending" credit back to about the 6th of August (as at this time- 17th August). Results for workunits prior to the 6th seem to all have credit granted. That's only 11 days lag between a workunit being sent to you (not sent, processed and returned) and credit being granted for it. Not so bad.

In the BOINC system there are bound to be small disparities between the rate at which WU's can be generated, returned, validated etc. We're just seeing one. Of course we don't want to see this queue grow forever, but the BOINC people will add more capacity for validation as the project grows. Hopefully soon.

I have discovered that the trick for me to handling the weekly outage is to pack the camper and take off to the Sierra's for a week of fishing. There by I can not see my "pending" and only feel frustrated when the fish are not biting. Of-course with a weekly shut down for maintenance, I would be out on the streams all the time, hmmmmm, sounding better already.

Nothing happens nothing helps. Maybe it&#180;s time to face the fact that there&#180;s nothing to be done to get rid of this mess.

Maybe stopping the project and deleting all the directories containing the results waiting for validation is the only option.

This whole thing is getting to suck... :-)

I wanna know how the weekly outage went. What they did, what effect it has shown yet if any.

That's hardly necessary. A few weeks ago (6-8) the validator queue was growing and someone did something to fix it. Then the backlog shifted somewhere else, but nonetheless it was fixed.

Last time I looked there were six "hosts" assigned as transitioners with no backlog reported for that process, but only four assigned as validators, though there are 940K results waiting for validation.

I hardly think that such a defeatist attitude is called for. We still don't know what actions were implemented during the outage or what else was learned. At the moment all we know is the backlog is still increasing.

Dave I have to agree with you about that remark.

Crunch3r it will be fixed in due time, just be patient. If you can't be patient you can work on another program until it is running better.

and interestingly, the WFV queue sometimes slows to a stop, but it never decreases...
